Specification:
Power supply: 12V DC / 50mA
Inputs: 2x analog with 1M pull-up resistor
Output: 1x SPDT contact 0.5A / 125VAC
Cover: KM-18B
Programmer: CH340 Serial Port Debugger USB to TTL Converter

Description:
The electronic module was originally designed as a staircase lighting switch. The module transforms the analog output from the FSR type pressure sensors into a two-state output with using of a relay.

The output is a relay potential-free changeover contact 0.5A / 125VAC. The module is compatible with the Arduino nano 328 module, but does not include a USB converter. Therefore, it is necessary to use a standard Arduino USB converter. The module contains a 3-pole DIP switch that can be used to set various program modes. The firmware for FSR sensor does not exist, but the firmware for the automatic switch of pump for disinfectant liquid exists.

The examples of other possibilities of use:

• thermostat
• automatic lighting with PIR sensor
• alarm with PIR sensor or radar
• twilight switch
• logger
• automatic watering system
• fluid flow measurement and automatic switching according to the volume of fluid
• automatic switch of a pump for disinfectant liquid, etc

All mentioned applications above depend on the firmware, which you have to create yourself.
